Emerson 960177-02

Yueyang Tongtu, as a long-term supplier of high-precision monitoring equipment accessories for overseas customers, offers the low-priced Emerson 960177-02. As a connection bridge between the probe and the preamplifier inside the control cabinet, it has an extremely tight shielding layer inside, which can effectively resist strong electromagnetic interference generated by power plant frequency converters and high-voltage motors.

Structure

This Emerson 960177-02 model has a high-temperature and oil-resistant colored insulation sheath on the outermost layer. When you peel off the outer layer, you can see an extremely tightly woven tin-plated copper shielding mesh. This mesh has a high density and its function is to keep external interfering electromagnetic waves out. Inside the shielding mesh, there is also an insulating medium, and the center of the medium is the very crucial internal coaxial core wire. For this extension cable, the diameter of the internal core wire, the material of the insulating medium, and the density of the shielding mesh all jointly determine the "characteristic impedance" of this wire. Only when these three parameters meet the strict standards, when it is connected to the on-site probe and the preamplifier in the cabinet, it can form a continuous impedance closed loop, otherwise, the signal will suffer severe distortion during transmission.

Performance

This Emerson 960177-02 model has extremely excellent anti-interference performance and signal fidelity. Because its internal coaxial structure and shielding layer are well-standardized, it can accurately and without any attenuation send the minute axial vibration changes sensed by the on-site probe to the preamplifier located tens of meters away. In those environments with extremely harsh electromagnetic conditions, such as next to several tens of thousands of volts of high-voltage power lines in a cable tray, or beneath a large variable-frequency motor, as long as the shielding layer is reliably grounded with this 960177-02, it can suppress the interference signals to an extremely low level and will definitely not cause the monitoring system to display false values. Its physical weather resistance performance is also very robust. Whether exposed to the high-temperature environment outside the cover of the machine or immersed in a conduit pipe that may have a small amount of oil leakage, its outer skin will not crack, and the internal insulation resistance always remains at a very high safe value.
